AP-357 Power Supply Solutions for Flash Memory

Intel flash memory is rapidly being incorporated into a wide range of applications, adding enhanced capability to existing "traditional'' memory markets, and creating new markets that exploit its benefits. Sometimes the application requires fast writes and the target design platforms may not possess the low powered 12V supply for programming and erasing flash memory at highest performance. The system design engineer then needs to identify a power conversion solution with features and capabilities matching the needs of the application. For example, portable equipment requires a power supply converter that minimizes size and weight, maximizes efficiency to extend battery life, and can be switched into a standby mode to conserve power. The following application note presents some state of the art DC- DC converter solutions.
